(IRNA) - Secretary of the Supreme National Security Council (SNSC) Ali Larijani said in Tehran on Tuesday that the time was ripe for the United States to change its attitude in the region, and offered Iran's help in this regard.
Larijani was speaking to reporters on the sidelines of an ongoing international conference dubbed `Iran's Nuclear Energy Program: Policies and Prospects' which kicked off here Tuesday morning.
"The US attitude has led to mistrust at the highest level in the region. If Al-Qaeda was in the minority before, the fact is it has now established a base in the region as a result of the US' behavior," he said.
Larijani stressed that the US' attitude toward issues has promoted terrorism in the region.
"The Taliban was set up with US assistance but today US officials can no longer deny their mistake."
Pointing to US moves in Iraq, he said: "We supported the political process leading to the formation of the government in Iraq but surprisingly US Secretary of State Condoleezza Rice and British Prime Minister Tony Blair arrived in Baghdad at night to establish a government."
"Their (US and allies) Zionist advisors have led to their making such mistakes in the Middle East region," Larijani said.
In response to a question on US efforts to draw Europeans to their side in the nuclear standoff with Iran, the SNSC secretary said: "The US has no need to encourage the Europeans. This will have no advantage for Europe."
He said "Europe is wise to the extent that it is currently following up settlement of Iran's nuclear case although it is under US pressure."
"The Islamic Republic of Iran does not want to humiliate any country. The US should know it will lose its prestige in the world if it attacks Iran," he said.
"We are ready for a reasoned approach and for peaceful means to settle the issue but will give an appropriate response if the US uses tough language."
He warned the US against using threats "to deter Iran from its path," saying it should ponder its moves and weight their consequences.
"If the US decides to impose sanctions on Iran, we will halt our cooperation with the International Atomic Energy Agency (IAEA)," he declared.
He stressed that Iran would stop using kind language if it were subjected to bullying and violence.
The SNSC secretary rejected allegations of any covert nuclear activity in Iran, saying "all nuclear activities of the country, including those carried out in Isfahan's Uranium Conversion Facility, (UCF) have been under IAEA surveillance."
"With regard to Natanz, based on the Non-Proliferation Treaty (NPT), there was no need to announce activities since we did not carry out injection. Injection of gas into centrifuges has not been conducted since a few days ago," Larijani added.
Asked when Majlis would approve the Additional Protocol to the NPT, he said that the "government had previously ratified the protocol. Processes are also currently underway in Majlis in this regard."
"This shows Iran's determination to ratify the protocol which it regards as an important step. But certain countries, including Israel, have not ratified it even in their parliaments."
